Juice lime into a blender. Add raspberries, sugar, and vanilla; blend until smooth.
3 tbsp granulated sugar
½ tsp vanilla extract
Pour raspberry-lime pureé into a strainer placed over a medium bowl. Using a silicone spatula, press pureé through the strainer to remove seeds; discard seeds and set sauce aside.
Peel and slice mango flesh away from the pits, starting with the flat sides; medium dice.
Trim, peel, and small dice kiwis.
To serve, place one scoop of ice cream in the bottom of each bowl; top with half the raspberry-lime sauce and the diced fruit. Place a second scoop of ice cream on top, drizzle with remaining sauce, and enjoy!
